Adam Clarke on Psalms 14:6

Ye have shamed the counsel of the poor - Instead of תבישו tabishu, "Ye have shamed," Bishop Horsley proposes to read תבישם tabishem, and translates the clause thus: "The counsel of the helpless man shall put them to shame." But this is not authorized by MS. or version. There is no need for any change: the psalmist refers to the confidence which the afflicted people professed to have in God for their deliverance, which confidence the Babylonians turned into ridicule. The poor people took counsel together to expect help from God and to wait patiently for it; and this counsel ye derided, because ye did not know - did not consider, that God was in the congregation of the righteous.
